Thankfully, anime often repeats the same images, or the same parts of images to do its animation. Download the shareware program Unique Filer in order to find duplicate images. If you can find duplicate images, then you will only need to edit one of them, and then replace the duplicates with your edited one.

So, I read about the "Unique filer" for Virtual Dub, how it removes multiple copies of the same frame, and I really wanna find it.

Don't think for a second that I didn't try looking using a search engine. I scavaged through a lot of nothing for quite some time. It's such a headache. :mad:
